Pass the 1.6 mm guide pin with pull-through suture (attached
to the Mini TightRope) from lateral (2nd metatarsal) to medial
(1st metatarsal) and stop before the button enters the drill hole.

The Oblong Button is flipped upon exiting the medial side of
the first metatarsal cortex. Apply lateral tension on the blue
suture. This will help seat the Oblong Button against the bone.

Surgical Technique
The pull-through suture can now be advanced while the guide
pin is pulled medially. At the same time, apply lateral tension
on the blue suture just behind the oblong button. This will
help the oblong button to lie sideways, and pass easily through
both bone tunnels.
Suture Passing Option (e):
The guide pin can be removed, leaving just the white pull-
through suture. A straight Micro SutureLasso can then be
used to pass the suture through both bone tunnels.
The white pull-through suture is cut and removed. The surgeon
should manually push the 1st metatarsal and the 2nd metatarsal
together to correct the intermetatarsal angular deformity. Once
fluoroscopy confirms proper positioning, the trailing Round
Button is tightened down by applying gradual tension on the
remaining two strands of blue suture. Tie 2-3 half hitches and
cut the suture. Any previously placed sutures incorporating
the lateral capsule of the 1st metatarsal, the adductor tendon
and the medial capsule of the 2nd metatarsal are now tied thus
completing the repair.
